1. INTRODUCTION
This user and maintenance manual refers to the IN’PULSE lubrication system.
This manual should be conserved in such a way that it remains undamaged over time and is readily available to
personnel needing to consult it.
The manufacturer reserves the right to update the product and/or the user and maintenance manual without the
obligation to revise previous versions. Further copies of this manual, updates or clarifications can be obtained by
directly contacting Experts & Tools at NTN-SNR Roulements, or to consult our web site at www.ntn-snr.com.
The use of the equipment referred to in this manual must be entrusted to qualified personnel with a basic knowledge
of mechanics, hydraulics and electrical systems.
It is the responsibility of the installer to use tubing suitable for the system; the use of inadequate tubing can cause
problems with the pump, injury to persons and create pollution.
Loosening of connections can cause serious safety problems; carry out a check before and after installation and, if
necessary retighten them.
Never exceed the maximum working pressure values permitted for the panel and the components connected to it.
Before any maintenance or cleaning operation disconnect the power supply, close off the air supply and discharge
the pressure from inside the equipment and the tubing connected to it.
Do not subject the panel, the connections, the tubing or parts under pressure to violent impacts; damaged tubing or
connections are dangerous and should be immediately replaced.
After long periods of inactivity, check air tightness of all parts subjected to pressure.
Personnel must use personal protection equipment, clothing and tools adequate for the location and the use of the
panel both during its operation and during maintenance operations.
The panel, and any accessories mounted on it, should be carefully checked immediately on receipt and in the event
of any discrepancy or complaint the NTN-SNR Roulements Sales department should be contacted without delay.
NTN-SNR Roulements declines to accept any responsibility for injuries to persons or damage to property in the
event of the non-observance of the information presented in this manual.
Any modification to component parts of the system or the different destination of use of this system or its parts
without prior written authorization from NTN-SNR Roulements will absolve the latter from any responsibility for injury
to persons and/or damage to property and will release them from all obligations arising from the guarantee.
2. GENERAL DESCRIPTION
The Duo’Pulse lubrication pump may be adapted to many uses without making any mechanical changes even after it
has been installed. In fact, the pressure, quantity of lubricant delivered, actual type of lubricant or type of distribution
can be altered.
This construction technique is essentially based on the following modules:
• Electric motor
• Pump body with integrated reducer
• Two pumping elements
• Reservoir
• Valves and outlet unit (inverter, pressure adjustment valve, etc.).
There is only one bearing structure for all versions, with the dual pumping element constituting the essential module.
The pump unit possesses one single output, because the deliveries from the two pumping elements flow into a
manifold unit.
The pump is controlled by normal electrical apparatus which is able to effect inversion and perform the programmed
cycles.
The Duo’Pulse electric pump is fully protected against the external environment and can operate without difficulty
under the most severe environmental conditions.
